[PATCH 2.6.22 REGRESSION] Fix slab redzone alignment

2007-07-04 Thread David Woodhouse
Commit b46b8f19c9cd435ecac4d9d12b39d78c137ecd66 fixed a couple of bugs by switching the redzone to 64 bits. Unfortunately, it neglected to ensure that the _second_ redzone, after the slab object, is aligned correctly. This caused illegal instruction faults on sparc32, which for some reason not enti

Hi David, I have sucessfully tested the attached patch on Sparc32:sun4c. Is there any chance of this getting sufficiantly tested on other architectures to get in into v2.6.22 ? Regards Mark Fortescue.From: Mark Fortescue <[EMAIL PROTECTED]>, David Woodhouse <[EMAIL PROTECTED]> Veriou

Hi David, Another related point that may also need to be considered is that I think I am correct in saying that on ARM and on the 64bit platforms, sizeof (unsigned long long) is 16 (128bits). Should the RedZone words be specified as __u64 not the unsigned long long used or does the alignment
